Reflection Nebulae

Polarization mapping of some reflection nebulae (e.g., NGC 6729) reveals parallel bands of polarization vectors across pre-main sequence stars (Ward-Thomson et al. 1985, Mon. Not. R. Astr. Soc., 215). These authors have suggested a model in which the bands would be. Explained by dust discs, the grains being aligned by toroidal magnetic fields ∼ 102 μG.
